“It was one of the best performances of the season,” Pochettino said. “We thoroughly deserved the result.

“When you sign players you expect them to make a big impact in the team. We are very happy with him [Son].

“He has adapted to the team very well. After scoring twice in the Europa League he scored again and when you arrive at the club as a striker that’s very good.

Asked about Kane, who continues his search for a goal at club level this season, Pochettino responded: “I am not concerned [about Kane]. Maybe he is a little bit because he’s a striker but it’s only a matter of time before he scores again.”
